PHP scripts and programs for Beginner to Master

Have you ever came across a situation where you need to truncate the large text and show the "read more.." link to redirect user to read the full post ?
I know you might be searching for a function to show read more link in php.

Here is our simple function which can be used to show the "Read more.." links dynamically.

<br /><br /><?php<br />//function to truncate text and show read more link<br />function truncate($mytext,$link,$var,$id) {<br />//Number of characters to show<br />$chars = 25;<br />$mytext = substr($mytext,0,$chars);<br />$mytext = substr($mytext,0,strrpos($mytext,' '));<br />$mytext = $mytext." <a href='$link?$var=$id'>read more...</a>";<br />return $mytext;<br />}<br />?><br /><br />

The above function can be used anywhere to show read more links with dynamic mysql queries.

How to use this function ???
Here is a simple example to do this
First you will need to create the connection with the database.
Connection settings are stored in "connect.php" file

<br /><br /><?php<br />include "connect.php";<br />$sql = "SELECT * FROM articles";<br />$result = mysql_query($sql);<br />while($row = mysql_fetch_array($result))<br />{<br />echo "\n";<br />echo truncate($row['article_text'],"article.php","article_id",$row['article_id']);<br />}<br /><br />//function to truncate text and show read more link<br />function truncate($mytext,$link,$var,$id) {<br />//Number of characters to show<br />$chars = 25;<br />$mytext = substr($mytext,0,$chars);<br />$mytext = substr($mytext,0,strrpos($mytext,' '));<br />$mytext = $mytext." <a href='$link?$var=$id'>read more...</a>";<br />return $mytext;<br />}<br />?><br /><br />


This will output your article text with proper linking to original post with read more link.

Even you can customize the truncate function for more security check and customizing your display.

Following things are required for using php on windows

Hi Friends, programming-in-php.blogspot.com is a place to share experience and knowledge.

At many places we require the contact us or feedback form to get some input from the user or to get some feedback from the user.
Today i will be showing you how to create a very simple feedback form or contact us form in php with the mail function and without any database.

1) First we will be creating a simple form to accept the user input like name, email and their message or feedback or query.

  

    
Name : 
    
"/>
  
  

    
Email : 
    
"/>
  
  

    
Message : 
    
<?php echo $_POST["message"]; ?>
  
  

    
 
    

  

2) In the form tag we have not specified any action part and we kept action="" in the form tag, so when the form is submitted at that time it will call itself.
So on submit we will execute our code to send the mail.

3) some css for the form and good look.

.textbox,.textarea {

width:300px;

border:solid 2px #00CCFF;

padding:3px;

margin:10px;

}

.error {

background: #FBBFDC;

color:#EF013D;

border:solid 1px;

padding:5px;

margin:5px;

}

4) After the page is submitted we will process the form data.

<br /> <br /><?php <br />if(isset($_POST["Submit"])) <br />{ <br /> $email = $_POST["email"]; <br /> $msg = $_POST["message"]; <br /> $username = $_POST["name"]; <br /> if($username!="" and $email!="" and $msg!="") <br /> { <br /> sendmail($username,$email,"",$msg,""); <br /> } <br /> else <br /> { <br /> echo "<div class='error'>Fill all the fields ! Thank you.</div>"; <br /> } <br />} <br />?> <br /> <br />

5) When the form is filled then we will be calling a function sendmail.

<br /> <br /><?php <br />function sendmail($username,$email,$data,$msg,$footer) <br />{ <br /> $to="youremailidhere"; <br /> $headers = "MIME-Version: 1.0\r\n"; <br /> $headers .= "Content-type: text/html; charset=iso-8859-1\r\n"; <br /> //$headers .= "From: ".$from."\r\n"; <br /> $headers .= "From: $username <$email>\r\n"; <br /> $headers .= "Reply-To: youremailidhere\r\n"; <br /> <br /> $body="<div align=left><p>Dear Admin,</p>"; <br /> $body.="<p>Message from : $username</p>"; <br /> $body.="<p>Email id : $email</p>"; <br /> $body.="<p>Message : $msg</p>"; <br /> <br /> $body.="Feedback end</p>"; <br /> <br /> if(@mail($to,'feedback from http://programming-in-php.blogspot.com',$body,$headers)) <br /> { <br /> echo "Thank you for your valuable feedback !"; <br /> } <br /> else <br /> { <br /> echo "<div class='error'>Can't send email ! ! !</div>"; <br /> } <br />} <br />?> <br /> <br />

Finally, merge all the code to create a simple contact us form or feedback form.
Full source code is here for your reference

.textbox,.textarea {

width:300px;

border:solid 2px #00CCFF;

padding:3px;

margin:10px;

}

.error {

color:#EF013D;

border:solid 1px;

padding:5px;

margin:5px;

}

























  

    
Name : 
    
"/>
  
  

    
Email : 
    
"/>
  
  

    
Message : 
    
<?php echo $_POST["message"]; ?>
  
  

    
 
    

  






if(isset($_POST["Submit"]))

{	

	$email = $_POST["email"];

	$msg = $_POST["message"];

	$username = $_POST["name"];

	if($username!="" and $email!="" and $msg!="")

	{

		sendmail($username,$email,"",$msg,"");

	}

	else

	{

		echo "
Fill all the fields ! Thank you.
";

	}

}

function sendmail($username,$email,$data,$msg,$footer)

{		

		$to="youremailidhere";

		$headers  = "MIME-Version: 1.0\r\n";

		$headers .= "Content-type: text/html; charset=iso-8859-1\r\n";

		//$headers .= "From: ".$from."\r\n";

		$headers .= "From: $username <$email>\r\n";

		$headers .= "Reply-To: youremailidhere\r\n";



		$body="
Dear Admin,
";

		$body.="
Message from : $username
";

		$body.="
Email id : $email
";

		$body.="
Message : $msg
";

		

		$body.="Feedback end
";



		if(@mail($to,'feedback from http://programming-in-php.blogspot.com',$body,$headers))

		{

			echo "Thank you for your valuable feedback !";

		}

		else

		{

			echo "
Can't send email ! ! !
";

		}

}

sometimes it is required to get the current working directory of the script.
so to get the current working directory in php this is a small function.

<br /><br /><?php<br />echo getcwd();<br />?><br /><br />
